Description
The central theme of this course is Vitalik’s idea of a decentralized computer system, achieved by deploying software programs, called “smart contracts,” into blocks and executing them during the mining process. You’ll learn the logic of smart contracts by playing with fun demos. You’ll also gain insights into the broader advantages and limitations of decentralization and smart contract technology.
